PyBench takes a long time to run, also upstream have removed it from Python and instead use test.regrtest —pgo to profile the interpreter. The results are good: not only does Python compile faster (~300s vs ~600s on my machine) but Phoronix’s PyBench test runs in 2130ms compared to 2229ms when using PyBench to train (and 2345ms with PGO disabled).

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
